Judge Andrews Construes Claim Term in Veramyst ANDA Case
Judge Andrews has issued a claim construction opinion in the ANDA dispute between GlaxoSmithKline and Sandoz over GSK’s Veramyst product. The parties disputed construction of only a single term, “at around.” Judge Andrews agreed with Sandoz that the phrase “at around” indicates a well-established margin of error in the context of X-Ray Powder Diffraction, the method indicated by the patents-in-suit for distinguishing various forms of fluticasone furoate. Because the intrinsic and extrinsic evidence supported the view that a separation of .2 degrees is reliably distinguishable, Judge Andrews concluded that Sandoz’s construction requiring a margin of error of only .1 degrees was correct.
